Statistical Traffic Control for Cognitive Radio Empowered LTE-Advanced with Network MIMO
Shao-Yu Lien and Kwang-Cheng Chen, Fellow, IEEE
Abstract—Deploying 3GPP LTE-Advanced to the ISM band
resolves the deployment issue of obtaining feasible bandwidth
from crowded spectrum. However, considering that wireless local
area networks (WLANs) have been deployed to the ISM band,
recent researches show that LTE-Advanced needs to provide communication
opportunities for WLANs. Such a coexistence relies
on applying the cognitive radio technology to LTE-Advanced.
However, the cognitive channel access leading to severe channel
availability variation obstructs quality-of-service (QoS) guarantees
in LTE-Advanced. To alleviate channel availability variation,
we adopt a powerful technology known as the network multipleinput-
multiple-output (MIMO) and propose the statistical traffic
control scheme comprising the packet transmission scheduling
and the admission control for LTE-Advanced to tackle critical
challenges of the packet transmission coordination and the radio
resources allocation in the network MIMO. Simulations results
demonstrate an effective support of voice and video transmissions,
thus enabling a successful coexistence with WLANs.
